Abstract
A multi-illuminated pushbutton, including a substrate having a switch and a button cap. A lighting board may be affixed to the substrate, the lighting board having a first light source, a second light source, and a through channel disposed between the first light source and the second light source. The button cap can have a first window for transmission of light from the first light source, a second window for transmission of light from the second light source, and a button base disposed through the channel of the lighting board and in operable relation with the switch. The button base can be shaped to prevent substantially all light emitted from the first light source from transmission through the second window and prevents substantially all light emitted from the second light source from transmission through the first window.
